• Do not let the jumper cables or other attached appliances get wet.
• Do not wear vinyl clothing when jumpstarting—friction can cause static
electricity sparks.
• Remove all metal jewelry to avoid short circuits.
• Always use safety glasses when jumpstarting battery. Keep battery terminals clean and be
careful to keep corrosion from coming in contact with eyes—acid can cause blindness and/
or severe burns.
• Never allow red and black clamps to touch or connect to the same piece of metal—this can
cause short-circuits, power arcing, and/or explosion.
• Make sure someone is available to give assistance if needed.

Operation
CAUTION: If the engine fails to start after three attempts, discontinue jumpstart procedure�
Excessive engine cranking can damage the vehicle’s starter motor� Look for other problems
that may need to be corrected or call for professional service�
1. Review the Jumpstarter warnings.
2. Put the vehicle’s gear in “park” position and make sure the brake is set.
3. Turn off the vehicle ignition and accessories (e.g. radios, lights, air conditioners), and
disconnect all devices such as GPS and mobile phones or tablets.
4. Turn off all Power Dome switches and disconnect all accessories.
5. Determine the polarity of the vehicle’s battery terminals. The positive (POS, P, +) battery
terminal is usually larger in diameter than the negative (NEG, N, −) terminal. If you are
unsure, you should refer to the vehicle owner’s manual.
6. Determine the ground system of your vehicle.
• If vehicle to be started has a negative ground system (this is most common)
a. Connect the red (+) cable clamp first to the vehicle’s positive (red) battery terminal.
b. Next, connect the black (−) clamp to the vehicle chassis or solid, non-moving,
metal vehicle component. DO NOT clamp directly to positive battery terminal or a
moving part.
• If vehicle to be started has the positive battery terminal connected to chassis (this is rare
and usually found in older car models from the 1950s or earlier):
c. Connect the black (−) clamp first to vehicle battery’s negative (black) terminal.
d. Connect red (+) clamp to the vehicle chassis or a solid, non-moving, metal vehicle
component. DO NOT clamp directly to positive battery terminal or a moving part.
